To understand the processes
governing electrodynamics of the
equatorial ionosphere as a
function of local time, longitude,
magnetic activity, and season
To understand the Solar Wind –
Magnetosphere – Ionosphere
coupling impact on the equatorial
density distributions that
important for the communication
and navigation systems
Objective of iMAGS magnetometer Array
To estimate the plasmasphere mass density
To monitor the GIC currents not only at high latitudes but also
at the equatorial region where the GIC get amplified by EEJ in
the same it gets amplified by AE at high latitudes

AMBER data coverage until Yesterday
Two prominent problems
Power fluctuation issue: Lack of funding to augment it with solar panel
Internet Connectivity issue: Expensive to use other alternative options
